Summary
Some spam messages cannot be blocked by IMSS because the mail subject and message body are constantly changing. The spam mails also contain spoofed header information, such as data from address with the domain portion also changing to random spoofed domains.
Here is an example of an email that needs to be blocked by the IP address:
Microsoft Mail Internet Headers Version 2.0
Received: from sdmxmc-01t.NOC.local ([xxx.xx.x.xxx]) by sdnoce2k3.NOC.local with Microsoft SMTPSVC(6.0.3790.1830);
Thu, 21 Aug 2008 14:18:38 -0400 Message-ID:<2ee8e3640002fe43@noc.local>
Received: from web54502.mail.re2.yahoo.com (web54502.mail.re2.yahoo.com [xxx.xxx.xx.xxx])
The IP address to be blocked in this example is [xxx.xxx.xx.xxx].
